Which is Bank 1 on S65?

[Etansinsta]

Made a thread earlier about code p0141 but have now determined the sensor needs to be replaced.

Having trouble determining which sensor needs replacing. The code says Bank 1 Sensor 2

Would that be the passenger side secondary cat sensor?

Thanks in advance

Passenger Side is bank 1; Sensor 2 would be the PostCAT O2 Sensor I believe.

I see you're in N.Van I could use ISTA+ to actually confirm it for you since I'm local.

The secondary cat doesn't have a sensor.

Bank 1 = Passenger side
Sensor 2 = Post cat sensor

Thank you! I did clear that up with real oem eventually last night haha.

I was going to have Gary scan it but I feel like the code is specific enough and will likely just replace the post cat sensor as it's only ~$100.

As I should know I've cleared the code and drove today and received p2451 code a bank 2 sensor 1 now.

Anyone have any thoughts?
